The cost to replace a catalytic converter on a 2008 Honda Accord varies by engine type (4‑cylinder vs. V6), the source of the part (aftermarket vs. OEM), and your region. In general, parts costs plus labor fall into a few broad ranges: a single aftermarket cat is typically around $150–$350, an OEM Honda cat is about $600–$1,000, and if your model uses two catalytic converters, parts can run roughly $700–$1,800 for aftermarket or $1,200–$2,000 for OEM. Labor commonly adds another $100–$300 for a single-cat replacement and $250–$900 for a dual-cat replacement. Prices vary, so shoppers should obtain multiple quotes and confirm exact part configuration for their vehicle.
What affects the price
Several factors drive the final price for a catalytic converter replacement on a 2008 Accord, including the engine configuration, the number of catalytic converters, the part source, and regional labor rates. California and other CARB-governed states can also influence pricing due to certification requirements.
Engine configuration and number of converters
4‑cylinder Accords typically have one catalytic converter, while some V6 configurations with dual exhaust can use two. The number of converters directly impacts both the part cost and the labor required for installation.
Region and regulatory requirements
In states with emissions regulations (like California), buyers may need CARB-certified replacements. This can raise the price and limit aftermarket options, though certified parts are required for street use in those states.
Parts options: OEM vs aftermarket
Below are the typical price ranges for catalytic converters on a 2008 Honda Accord, depending on configuration and part source. Prices are for parts only; labor is explained separately above.
- Single catalytic converter, 4‑cylinder (aftermarket): $150–$350
- Single catalytic converter, 4‑cylinder (OEM Honda): $600–$1,000
For a 4‑cylinder with a single cat, this is the most common scenario and usually cheaper to replace. The following ranges apply if your car uses two converters (common on some V6/dual-exhaust setups).
- Two catalytic converters, aftermarket (both cats): $700–$1,800
- Two catalytic converters, OEM (both cats): $1,200–$2,000
In practice, the total price for a dual-cat replacement includes both parts and labor and can vary widely depending on shop rates and exact vehicle configuration.
Labor costs and installation
Labor costs depend on how accessible the exhaust system is, whether sensors or wiring need attention, and the local shop rate. The following provides a rough guide for typical installations.
- Single-cat replacement (4‑cylinder): about 1–2 hours; labor roughly $100–$250
- Dual-cat replacement (V6): about 2–4 hours; labor roughly $200–$450
Combined with the part costs, a single-cat replacement often lands in the $250–$1,300 range, while a dual-cat replacement can total roughly $1,000–$2,800 depending on parts and labor in your area.
California and CARB considerations
California and some other states require CARB-certified catalytic converters for street use. If you live in CA, ensure the part includes CARB approval (an EO number) and is compatible with your vehicle’s VIN. This certification can influence both availability and price, and it may limit the pool of aftermarket options.
Where to buy and installation tips
To get the best price and ensure a proper fit, shop around and compare quotes from multiple shops. Consider these tips when buying and planning installation:
- Confirm whether your Accord uses one or two catalytic converters before buying; verify by inspecting the exhaust layout or checking the VIN.
- Decide between OEM and aftermarket. If you’re in CA, verify CARB certification for any aftermarket part.
- Request quotes that include both parts and labor, and ask about sensor compatibility and warranty on the part and the workmanship.
- Check for core charges and availability, as these can affect the upfront price but may be credited back when you return the replaced converter.
Getting multiple quotes and confirming the exact converter configuration for your car will help you avoid overpaying and ensure you get a compliant, long-lasting replacement.
Summary
For a 2008 Honda Accord, catalytic converter pricing hinges on engine type, the number of converters, and whether you choose aftermarket or OEM parts. Typical ranges (parts only) are: $150–$350 for a single aftermarket cat, $600–$1,000 for an OEM single cat, $700–$1,800 for two aftermarket cats, and $1,200–$2,000 for two OEM cats. Labor usually adds about $100–$300 for a single-cat job or $250–$900 for a dual-cat job. In California and similar markets, CARB-certified replacements are often required and can affect both price and options. Always obtain several quotes and confirm the exact part configuration for your vehicle to get an accurate total.
